Exothermic reaction - Wikipedia

An exothermic reaction is a chemical reaction that releases heat. It gives net energy to its surroundings. That is, the energy needed to initiate the reaction is less than the energy released. When the medium in which the reaction is taking place gains heat, the reaction is exothermic.
